流体機械に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scroll fluid machine that maintains a hermetic seal by applying a fluid pressure to a back surface of an orbiting scroll, and in particular, a structure that controls a capacity in a wide range of rotation speed. Related to a scroll fluid machine.

間から背圧室に流入する。In the above prior art, in order to use the pressure of the closed space higher than the suction pressure and press the orbiting scroll against the fixed scroll to maintain the hermetic seal in the axial direction, the fluid in the closed space is passed through a communication hole having a throttling action to pass through the orbiting scroll back. The orbiting scroll is introduced into the pressure chamber and pressed by the fluid pressure toward the fixed scroll. Here, the pressure in the closed space while communicating with the closed space with the communication hole changes with the turning of the orbiting scroll, and there is a minimum pressure and a maximum pressure. Therefore, when the pressure in the closed space is lower than the pressure in the back pressure chamber, the fluid flows out of the back pressure chamber through the communication hole into the closed space, and conversely, flows into the back pressure chamber from the closed space.

となる。In the case of a conventional scroll fluid machine that is operated at a constant speed, the size of the communication hole is appropriately determined, and the expansion effect causes the expansion of the fluid generated by the fluid entering and exiting the back pressure chamber and the enclosed space. And the power loss due to recompression was able to be at a level which was practically no problem. However, in the case of controlling the displacement by changing the rotation speed of the scroll fluid machine in a wide range, the loss due to the fluid movement described above becomes a non-negligible level, especially during low-speed operation.

Following the orbiting motion of the orbiting scroll, the opening of the communication hole on the back pressure chamber side is opened to the space communicating with the back pressure chamber only when the pressure in the closed space is close to the back pressure chamber pressure, and The back pressure chamber is communicated to maintain the back pressure chamber pressure and reduce power loss generated through the communication hole.
